Photuris mysticalampas sp. nov., is described herein. This species can be distinguished from other Photurids by the combination of its small size, oval body shape, the dense pubescent appearance of the elytra, and flash pattern. Adults emerge at night from Sphagnum spp. hummocks in acidic peatland floodplain forests and fly slowly among dense understory vegetation at <2m height. Typical flash pattern is a slow signal (0.4 – 0.8 sec) of moderate luminosity for a Photuris repeated at 3 – 7 sec intervals. The species is known only from three sites in two watersheds in Sussex County, Delaware.

Anew species, Micropselapha bohemica sp. n. (Diptera, Scathophagidae) is described from the Czech Republic. Figures of both male and female terminalia are provided together with a habitus image. The genus is redefined and important morphological characters are discussed. A key to all three known world species is provided.

We observed the antennal morphology and sensilla of the black-back prominent moth, C. anastomosis, by scanning electron microscopy (SEM). Antennae of both sexes of C. anastomosis are bipectinate, feather-like in shape, consisting of two basal segments, scape and pedicel, followed by a long distal flagellum with more than 30 segments, each having a pair of lateral branches. Twelve major sensillar types were identified: two types of sensilla trichodea (ST), two types of sensilla chaetica (SCh), three types of sensilla squamiformia (SSq), two types of sensilla basiconica (SB), two types of Böhm bristles (BB), sensilla coeloconica (SCo), sensilla auricillica (SA), sensilla styloconica (SSt), sensilla cavitata-peg (SCP), sensilla gemmiformia(SG), sensilla basiconic-mastoid (SBM) and sensilla cylindrica (CY). Sensilla cylindrica and sensilla gemmiformia only exist on female antennae, while sensilla basiconic-mastoid are only on male antennae. The morphology, number and distribution of various sensilla between two sexes were compared and their possible functions are discussed.

The male, female, and larva of Micrasema florida, n. sp. (Trichoptera: Brachycentridae), is described from Coastal Plain streams of Alabama and the western Florida panhandle. The species belongs in the Micrasema rusticum Group and closely resembles Micrasema ozarkana Ross and Unzicker, 1965. The male lacks thick, sclerotized straps on abdominal segment IX. The female has anterior emarginations on the abdominal terga. The larva has a pale yellow head with light brown muscle scars and builds a case that is abruptly narrowed posteriorly.

The three larval instars of Brachyvatus acuminatus (Steinheil, 1869) (the type species of the bidessine genus Brachyvatus Zimmermann, 1919) are described and illustrated for the first time including detailed morphometric and chaetotaxic analyses of the cephalic capsule, head appendages, legs, last abdominal segment and urogomphi. Larvae of this genus are characterized by the absence of the primary pore ABc, which is a synapomorphy of the tribe Bidessini. Brachyvatus larvae can be separated from those of all other known Bidessini genera by the following combination of characters: very small size; lateral branches of nasale well visible in dorsal view; ventroapical spinula on third antennomere absent; meso- and metatergite of instar I with anterotransverse carina; siphon short; long urogomphi with secondary setae; seta PA3 absent; setae UR2 and UR4 inserted contiguously; natatory setae present on tibiae in instars II–III.

The distribution of Merope tuber in the Interior Highlands of the United States is presented showing this rarely collected species has a wider distribution than previously thought. Conservation organizations that list M. tuber as a species of concern, might wish to reconsider this classification until more thorough distributional surveys are conducted.

Biogenic amines regulate the behavior and physiology of animals, including the postmating behavior of females in some insect species. In the present study, biogenic amines were injected into the abdomens of Trigonotylus caelestialium females, and the effects on oviposition behavior were examined. Octopamine solution increased the number of eggs laid by females, and the effect was dose-dependent and repeatable. These results suggest that octopamine plays a role in the oviposition process after mating.
